MOTOROLA Chapter 1. Overview 1-13
Part I. Overview
In this application, the MPC8260 is connected to four TDM interfaces channalizing up to
128 channels. Each TDM port supports 32Ð128 channels. If 128 channels are needed, each
TDM port can be conÞgured to support 32 channels. This example has two MII ports for
10/100 BaseT LAN connections. In all the examples, the SCC ports can be used for
management.
1.7.1.3 LAN-to-WAN Bridge Router
Figure 1-5 shows a LAN-to-WAN router conÞguration, which is similar to the previous
example.
